Numerical Estimation of Bearing Capacity of Shallow Footings Resting on Layered Sand

In the present study, estimation of bearing capacity of strip footing and circular footing resting on layered sand following the non-associated flow rule (ψ < ϕ) is carried out by finite element analysis. This study provides insight into the variation of bearing capacity at the failure of the footing with change in footing’s shape, dense sand layer’s thickness, and friction angle of sand layers. The bearing capacity of footing on layered sand was expressed in terms of BCR (ratio of bearing capacity of the footing on layered sand to bearing capacity of homogeneous bottom layer). The magnitude of BCR for a selected range of friction angles was in the range of 2.48–20.28 for strip footing and 4.44–44.34 for circular footing. Furthermore, footing settlement on layered sand decreased up to 68.75% and 90.6% for strip and circular footing, respectively. The obtained results were compared with the literature wherever applicable.
